Hey BitcoinTalk,
I'm a software developer from the Netherlands. I have quite some experience building Bitcoin apps.
The app I'm most proud of is my
Kraken app which is a full-featured Bitcoin trading app for Windows Phone. It allows you to view the rates of all the cryptocurrency pairs on kraken, see your order history, place new orders, cancel orders, view candlestick charts, etc. It got really good reviews and the guys from Kraken loved it. It was the first Bitcoin trading app on Windows Phone and was picked up by a lot of big new websites such as windowscentral and wppoweruser. I had many requests from Android and iOS users to please port my app to their platforms (haven't done so because Kraken is working on their own official apps for those platforms).

I also freelanced for Coinbase and worked on a Windows app for them. Unfortunately they decide to focus on Android and iOS first, so I got permission to rebrand the app and launch it under my own name. I'm going to do so with the launch of Windows 10 Mobile in December, and it will be a native Bitcoin wallet.
For a client from the Netherlands (a pretty good Bitcoin exchange that allows you to buy Bitcoins with iDeal, they're called BitMyMoney and are working on their own hosted wallet service) I worked on an Android app that was built using Xamarin Forms (so it can be easily ported to iOS and Windows Phone).
I'd like to do more for the Bitcoin ecosystem because I love what I'm doing. If you think I can help your company develop a mobile app (or a non-mobile app), I'm available for freelance jobs. I'm an experienced full-stack C# developer. I know a lot about building native Windows apps and Xamarin cross-platform apps, but also about ASP.NET and Azure.
